Ultralong cerium-based coordination polymer (Ce-CP) nanobelts have been prepared from benzene-1,3-dicarboxylic acid (1,3-H₂BDC) and Ce(NO₃)₃via a facile solvothermal method, employing a cheap and non-toxic mixture of ethanol and water as solvent. The products were well characterized and analyzed. The nanobelts are dozens of micrometers in length, 50–200 nm in width, and 20–40 nm in thickness. Reaction parameters such as molar ratio of reactants, reaction temperature and time of preparation were also investigated in detail. CeO₂ nanobelts were obtained after calcining the CP nanobelts in air at 400 °C for 4 h. The activity of the catalytic reduction of p-nitrophenol by the 1 wt% Pt loaded CeO₂ nanobelts was investigated. Furthermore, other rare earth-based CP micro/nano structures were also prepared using this method.

通过配位聚合物前体法制备超长二氧化铈纳米带†

超低价铈基配位聚合物（Ce-CP）纳米带已通过简便的溶剂热法由苯-1,3-二羧酸（1,3-H ₂ BDC）和Ce（NO ₃）₃制备，采用廉价且廉价的方法。乙醇和水作为溶剂的无毒混合物。对产物进行了良好的表征和分析。纳米带的长度为数十微米，宽度为50-200 nm，厚度为20-40 nm。还详细研究了反应参数，例如反应物的摩尔比，反应温度和制备时间。将CP纳米带在空气中于400°C煅烧4小时后，获得CeO ₂纳米带。1 wt％负载的CeO催化对硝基苯酚的催化还原活性_{研究了2种}纳米带。此外，还使用此方法制备了其他基于稀土的CP微/纳米结构。
